Dear Hall Chadwick Acquisition Corp II

Hall Chadwick Acquisition Corp II (Company)

We are lawyers qualified to practise in the Cayman Islands and have acted as Cayman Islands legal advisers to the Company in connection with the Company’s registration statement on Form S-1 to be filed with the Securities and Exchange Commission (Commission) on or about the date of this opinion (Registration Statement), relating to the registration of:

1)	26,500,000 units consisting of:

one Class A ordinary share of the Company (Class A Share); and

one-half of one redeemable warrant (Warrant), each whole warrant entitling the holder to purchase one Class A Share at a price of $11.50 per share,

(Units) at an offering price of US$ 10.00 per Unit;

up to 3,500,000 additional Units, which the several underwriters, for which Cohen & Company Capital Markets, a division of Cohen & Company Securities, LLC is acting as representative (Representative), will have a 45-day option to purchase from the Company to cover over-allotments, if any (Over-Allotment Units);

3)	4,350,000 private placement Warrants each of which entitles the holder to purchase one Class A Share at a price of $11.50 per share (*Private Placement Warrants) to Hall Chadwick II LLC (Sponsor*);

4)	3,312,500 Private Placement Warrants (or up to 4,012,500 if the underwriters exercise their option to purchase Over-Allotment Units in full) to the Representative;

5)	all Class A Shares and Warrants issued as part of the Units (including any Over-Allotment Units));

6)	all Class A Shares that may be issued upon exercise of the Warrants included in the Units (including any Over-Allotment Units); and

7)	all Class A Shares that may be issued upon exercise of the Private Placement Warrants,

in each case under the United States Securities Act of 1933, as amended (Securities Act) and pursuant to the terms of the Registration Statement. In this opinion Companies Act means the Companies Act, as amended, of the Cayman Islands.

The Class A Shares underlying the Units and the Over-Allotment Units are referred to herein as the Unit Shares and the Class A Shares to be issued in accordance with the Warrants are referred to herein as the Warrant Shares.

We are furnishing this opinion as Exhibit 5.2 to the Registration Statement.

For the purposes of giving this opinion, we have examined the Documents (as defined in Schedule 1) which are all the documents which we consider necessary and appropriate for the matters set out in this legal opinion. We have not examined any other documents, official or corporate records or external or internal registers and have not undertaken or been instructed to undertake any further enquiry or due diligence in relation to the transaction which is the subject of this opinion.

In giving this opinion, we have relied upon the assumptions set out in Schedule 2 which we have not independently verified.

Based solely upon the foregoing examinations and assumptions and upon such searches as we have conducted and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3, we are of the opinion that under the laws of the Cayman Islands:

1	Existence and Good Standing. The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands.

2	Capacity and Power. The delivery of the Registration Statement by the Company and the performance of its obligations thereunder are within the corporate capacity and power of the Company and have been duly authorised and approved by all necessary corporate action of the Company.

3	Authorised Share Capital. Based on our review of the Mem & Arts, the authorised share capital of the Company is US$55,500 divided into:

(a)

500,000,000 Class A ordinary shares of a par value of US$0.0001 each (Class A Shares);

(b)

50,000,000 Class B ordinary shares of a par value of US$0.0001 each (Class B Shares); and

(c)

5,000,000 Preference shares of a par value of US$0.0001 each (Preference Shares).

4	Issued Securities. As of the date of the Certificate of Incumbency (as defined in Schedule 1), the Company has:

(a)

0 Class A Shares;

(b)

10,500,000 Class B Shares; and

(c)

0 Preference Shares,

issued and outstanding.

Class B Shares. The Class B Shares have been duly authorized and are validly issued, fully-paid and non-assessable. The issue of the Class A Ordinary Shares to be issued on the conversion of the Class B Ordinary Shares (Conversion Shares) has been duly authorised and, when such Conversion Shares are issued in accordance with the Mem & Arts and the names of the registered owners are entered in respect of such Conversion Shares into the Register of Members of the Company, the Conversion Shares will have been legally issued, fully paid and non-assessable (meaning that no additional sums may be levied in respect of such Conversion Shares on the holder thereof by the Company). The issuance of any Conversion Shares would not, as at the date of this opinion, be subject to any pre-emptive rights, rights of first refusal or similar rights under the Mem & Arts or the Companies Act.

Units, Over-Allotment Units, Unit Shares. The Units, Over-Allotment Units and Unit Shares to be issued by the Company, as contemplated by the Registration Statement, have been duly authorised and, when allotted, issued, and fully paid for in accordance with the Resolutions and any related agreement, and when the name of the shareholder is entered in the Register of Members, the Unit Shares will be validly issued, allotted, fully paid, and non-assessable and there will be no further obligation on the holder to make any further payment to the Company in respect of such Unit Shares.

Warrant Shares. The Warrant Shares to be issued by the Company, as contemplated by the Registration Statement, have been duly authorised and, when allotted, issued, and fully paid for in accordance with the Resolutions and the terms of the Warrants, and when the name of the shareholder is entered in the Register of Members, will be validly issued, allotted, fully paid, and non-assessable and there will be no further obligation on the holder to make any further payment to the Company in respect of such Warrant Shares.

Cayman Islands Law. The statements contained in the Registration Statement included, but not limited to those in the sections headed “Risk Factors”, “Proposed Business”, “Description of Securities”, “Cayman Islands Taxation”, “Legal Matters” and “Enforcement of Civil Liabilities”, insofar as such statements purport to summarise or describe the laws of the Cayman Islands and the Mem & Arts, are accurate and fairly represent in all material respects summaries of Cayman Islands laws and regulations and the Mem & Arts.

This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the Cayman Islands as they are in force and applied by the Cayman Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. Except as specifically stated herein, we express no opinion as to matters of fact.

In connection with the above opinion, we hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our name under the headings, “Risks Relating our Management Team”, “Certain Differences in Corporate Law” and “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act, as amended, or the Rules and Regulations of the Commission thereunder.

This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein.

This opinion shall be construed in accordance with the laws of the Cayman Islands.

Yours faithfully

/s/ Harney Westwood & Riegels (Cayman) LLP
