 Portfolio Management Risk: If the strategies used and investments selected by the Fund’s portfolio management team fail to produce the intended result, the Fund may suffer losses or underperform other funds with the same investment objective or strategies, even in a favorable market.

Risk [Text Block]

 Market Risk: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt securities.

Lord Abbett Diversification Shares: Core Completion Fund | New Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 New Fund Risk: The Fund is newly organized. There can be no assurance that the Fund will reach or maintain a sufficient asset size to effectively implement its investment strategy. In addition, until the Fund achieves sufficient scale, a Fund shareholder may experience proportionally higher Fund expenses than would be experienced by shareholders of a fund with a larger asset base.

Risk [Text Block]

 Completion Fund Risk: An investment in this Fund is not designed to be a complete investment program or a standalone investment. It is intended to be a component of a broader investment program for whose use the Fund is exclusively designed. The performance and objectives of the Fund should be evaluated only in the context of your complete investment program.

Lord Abbett Diversification Shares: Core Completion Fund | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Fixed Income Securities Risk: The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that issuers will fail to make timely payments of principal or interest or default altogether. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or general economic news due to their increased credit risk relative to other fixed-income investments. In addition, as interest rates rise, the Fund’s investments typically will lose value.

Lord Abbett Diversification Shares: Core Completion Fund | Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Credit Risk: Debt securities are subject to the risk that the issuer or guarantor of a security may not make interest and principal payments as they become due or may default altogether. In addition, if the market perceives a deterioration in the creditworthiness of an issuer, the value and liquidity of securities issued by that issuer may decline. To the extent that the Fund holds below investment grade securities, these risks may be heightened. Insured debt securities have the credit risk of the insurer in addition to the credit risk of the underlying investment being insured.

Lord Abbett Diversification Shares: Core Completion Fund | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Interest Rate Risk: As interest rates rise, prices of bonds (including tax-exempt bonds) generally fall, typically causing the Fund’s investments to lose value. Additionally, rising interest rates or lack of market participants may lead to decreased liquidity in fixed income markets. Interest rate changes generally have a more pronounced effect on the market value of fixed-rate instruments, such as corporate bonds, than they have on floating rate instruments, and typically have a greater effect on the price of fixed income securities with longer durations. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation, and changes in general economic conditions.

Lord Abbett Diversification Shares: Core Completion Fund | Liquidity/Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Liquidity/Redemption Risk: The Fund may lose money when selling securities at inopportune times to fulfill shareholder redemption requests. The risk of loss may increase depending on the size and frequency of redemption requests, whether the redemption requests occur in times of overall market turmoil or declining prices, and whether the securities the Fund intends to sell have decreased in value or are illiquid. The Fund may be less able to sell illiquid securities at its desired time or price. It may be more difficult for the Fund to value its investments in illiquid securities than more liquid securities.

Lord Abbett Diversification Shares: Core Completion Fund | Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Government Securities Risk: The Fund invests in securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities (such as the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), or the Federal Home Loan Mortgage Corporation (“Freddie Mac”)). Different types of U.S. government securities are subject to different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government would provide financial support.

Lord Abbett Diversification Shares: Core Completion Fund | Mortgage-Related and Other Asset-Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Mortgage-Related and Other Asset-Backed Securities Risk: Mortgage-related securities, including commercial mortgage-backed securities (“CMBS”) and other privately issued mortgage-related securities, and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates and economic conditions, including delinquencies and defaults. The prices of mortgage-related and other asset-backed securities, depending on their structure

and the rate of payments, can be volatile. They are subject to prepayment risk (higher than expected prepayment rates of mortgage obligations due to a fall in market interest rates) and extension risk (lower than expected prepayment rates of mortgage obligations due to a rise in market interest rates). These risks increase the Fund’s overall interest rate risk. Some mortgage-related securities receive government or private support, but there is no assurance that such support will remain in place.

Prospectus [Line Items]  
Risk [Text Block]

 Commercial Mortgage-Backed Securities Risk: CMBS include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in CMBS reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. The economic impacts of COVID-19 have created a unique challenge for real estate markets, with the transition to remote-working environments potentially negatively impacting the occupancy rates of commercial real estate. CMBS may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities.

Lord Abbett Diversification Shares: Core Completion Fund | Inflation-Linked Investments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Inflation-Linked Investments Risk: Unlike traditional fixed income securities, the principal and interest payments of inflation-linked investments are adjusted periodically based on the inflation rate. The value of the Fund’s inflation-linked investments may be vulnerable to changes in expectations of inflation or interest rates and there is no guarantee that the Fund’s use of these instruments will be successful.

Lord Abbett Diversification Shares: Core Completion Fund | Foreign and Emerging Market Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Foreign and Emerging Market Company Risk: Investments in foreign companies and in U.S. companies with economic ties to foreign markets generally involve special risks. These companies may be more vulnerable to economic, political, and social instability and subject to less government supervision, lack of transparency, inadequate regulatory and accounting standards, and foreign taxes. Foreign company securities also include American Depositary Receipts (“ADRs”), which may be less liquid than the underlying shares in their primary trading market. Foreign securities also may subject the Fund’s investments to changes in currency exchange rates. Emerging market securities generally are more volatile than other foreign securities, and are subject to greater liquidity, regulatory, and political risks. Investments in emerging markets may be considered speculative and generally are riskier than investments in more developed markets. Emerging markets are more likely to experience hyperinflation and currency devaluations. Securities of emerging market companies may have far lower trading volumes and less liquidity than securities of issuers in developed markets. In certain emerging market countries, governments participate to a significant degree in their respective economies. Action by these governments could have a significant adverse effect on market prices of securities and payment of dividends. Companies with economic ties to

emerging markets may be susceptible to the same risks as companies organized in emerging markets.

Lord Abbett Diversification Shares: Core Completion Fund | Foreign Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Foreign Currency Risk: Investments in securities that are denominated or receiving revenues in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency being hedged. Foreign currency exchange rates may fluctuate significantly over short periods of time.

Lord Abbett Diversification Shares: Core Completion Fund | Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Loan Risk: Investments in floating or adjustable rate loans are subject to increased credit and liquidity risks. Loan prices also may be adversely affected by supply-demand imbalances caused by conditions in the loan market or related markets. Below investment grade loans, like high-yield debt securities, or junk bonds, usually are more credit sensitive than interest rate sensitive, although the value of these instruments may be affected by interest rate swings in the overall fixed income market. Loans may be subject to structural subordination and may be subordinated to other obligations of the borrower or its subsidiaries.

Lord Abbett Diversification Shares: Core Completion Fund | Collateralized Loan Obligations and Other Collateralized Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Collateralized Loan Obligations and Other Collateralized Obligations Risk: An investment in a CLO can be viewed as investing in (or through) another investment adviser and is subject to the layering of fees associated with such an investment. The risks of investing in a CLO generally can be summarized as a combination of economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments, and include interest rate risk, credit risk, liquidity risk, prepayment risk, and the risk of default of the underlying asset, among others.

Lord Abbett Diversification Shares: Core Completion Fund | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

 Derivatives Risk: The risks associated with derivatives may be different from and greater than the risks associated with directly investing in securities and other investments. Derivatives may increase the Fund’s volatility and reduce its returns. Derivatives may not perform as expected and the Fund may not realize the intended benefits. Whether the Fund’s use of derivatives is successful may depend on, among other things, the portfolio managers’ ability to correctly forecast market movements, company and industry valuation levels and trends, changes in foreign exchange and interest rates, and other factors. If the portfolio managers incorrectly forecast these and other factors, the Fund’s performance could suffer. In addition, given their complexity, derivatives are subject to the risk that improper or misunderstood documentation may expose the Fund to losses.

Lord Abbett Diversification Shares: Core Completion Fund | High Portfolio Turnover Risk [Member]  
Prospectus [Line Items]

 High Portfolio Turnover Risk: High portfolio turnover may result in increased transaction costs, reduced investment performance, and higher taxes resulting from increased realized capital gains, including short-term capital gains taxable as ordinary income when distributed to shareholders.

Risk [Text Block]

 High Yield Securities Risk: High yield securities (commonly referred to as “junk” bonds) typically pay a higher yield than investment grade securities, but may have greater price fluctuations and have a higher risk of default than investment grade securities. The market for high yield securities may be less liquid due to such factors as interest rate sensitivity, negative perceptions of the junk bond markets generally, and less secondary market liquidity. This may make such securities more difficult to sell at an acceptable price, especially during periods of financial distress, increased market volatility, or significant market decline.
