What documents do I need to apply for Co-Ownership?

Co-Ownership is the shared ownership scheme in Northern Ireland, and applying for it means proving three things: who you are, where you live, and what you earn. Co-Ownership's own guidance says the application takes around 30 minutes to complete, that you can save your progress and come back to it, and that once all your documents are in, a decision takes up to 5 working days on average¹.

The core paperwork is short. You upload proof of identity, proof of current address, the last 3 months of payslips for all employment if you are employed, and the last 3 months of bank statements for all accounts¹. Self-employed applicants and company directors send the last 2 years of tax calculation summaries (SA302s) and the matching tax year overviews instead of payslips¹.

There is a fee, and it pays for a check of your income, outgoings and credit history³. If you apply with someone else, both of your Experian credit histories are reviewed during the application stage⁴. This page sets out what each document is for, what changes if you are self-employed or applying as a couple, and what happens after you submit.

Documents everyone needs: identity, address and income

Co-Ownership's acceptable documents list works on a two-list system for identity. You provide one item from List A and one from List B, or alternatively one item from List A and another item from List A that shows your current address on it¹. The scheme's own summary of the process puts it more simply: proof of identity, proof of address, and evidence of your income².

For identity, Co-Ownership states that it accepts a valid passport or UK driving licence⁴. That is a narrower list than some other financial products use. Credit unions, for example, usually ask for two recent documents to prove identity and address, which can include a student or work ID card, a bus pass or a birth certificate⁸. A basic bank account can be opened with a driving licence, a recent council tax bill, a recent letter about your benefits, a recent letter or statement from another bank, a recent utility bill or your TV licence⁹. Co-Ownership's list is tighter, so it is worth checking what you hold before you start.

For address, the wider market gives a sense of what counts as acceptable evidence: a recent gas or electricity bill or a TV licence¹⁰, or one or two of a recent utility bill, rental contract, or a benefits or state pension letter issued within the past 12 months¹¹. Mortgage lenders commonly ask for two documents as proof of address, such as a bank statement, utility bill, council tax bill or credit card statement, dated within the last three months¹².

Payslips or SA302s: income evidence for employed and self-employed applicants

What you send as income evidence depends entirely on how you earn, and Co-Ownership splits applicants into two groups.

If you are employed, you provide the last 3 months of payslips for all employment, plus the last 3 months of bank statements showing salary payments¹. The phrase "for all employment" matters: if you hold more than one job, Co-Ownership says you need to provide payslips and evidence for all sources of employment¹³. A second job is not ignored because the first one covers the main income.

If you are self-employed or a company director, you provide the last 2 years of tax calculation summaries (SA302s) and the corresponding tax year overviews¹. Company directors are asked for something extra on top: Co-Ownership also requires your last 3 months of payslips¹. That combination, two years of tax documents plus three months of payslips, reflects the fact that a director's income can arrive in more than one form.

The wider mortgage market asks for broadly similar evidence. Lenders typically want statements from an accountant, a tax return form SA302, plus supporting information such as bank statements and receipts from self-employed applicants¹². The two-year lookback is standard, because a single year's figures can be unrepresentative.

Evidence of savings and funds for your share

Beyond income, Co-Ownership may ask for proof of savings and other funds, and this sits in the "depending on your personal circumstances" part of its document list. The conditional items include residency documentation, proof of savings such as savings statements, proof of any other income such as benefit award letters, and, where relevant, a decree absolute, separation agreement or financial settlement documents¹.

If you are providing evidence of savings, the kinds of documents that count in a means-tested context are bank, building society or Post Office books or statements, investment and share certificates, National Savings Certificates, Premium Bonds, and annuity or trust fund documents¹⁵. A professional property valuation, other than for the property you live in, can also serve as evidence¹⁵.

Where money has moved around before an application, the paper trail matters. In benefit assessments, documents may be requested to show that ownership of property has been transferred to another person, deeds showing money has been given to another person in trust, settlement or as a gift, and receipts showing what cash or savings has been spent on¹⁶. The same principle applies to a mortgage-style application: a large, unexplained movement in your accounts invites questions, and a document that explains it answers them.

If you are applying as a couple and one of you has come out of a previous relationship, the separation paperwork is part of the conditional list rather than an optional extra¹.

Applying together: documents and credit checks for two applicants

Co-Ownership's rule on couples is not optional. If you are married, in a civil partnership, or planning to live with a partner, you need to apply together². Both applicants must meet the eligibility criteria, and Co-Ownership assesses your combined household income and outgoings, with both of you equally responsible for the mortgage, if there is one, and the rent payments⁴.

Both applicants' Experian credit history is reviewed during the application stage⁴. That means a joint application is assessed on two credit files, not one, and a thin or damaged file on either side affects the outcome. It is worth both applicants checking their Experian report before applying, which is what Co-Ownership itself suggests⁴.

The documents are the same for each applicant: identity, address and income evidence for both people, plus the conditional items where they apply. The application fee covers a check of your income, outgoings and credit history³.

Submitting your application: the fee, the credit check and a decision

You can apply in one of three ways. Co-Ownership says you can apply online through your online account, through a mortgage adviser, or by booking a face-to-face appointment at its Belfast office, where a team member completes the application on your behalf⁴. The route you choose does not change the documents required.

The application fee covers a check of your income, outgoings and credit history³. Once Co-Ownership has all your documents, application review takes around five working days on average², and the scheme says it takes up to 5 working days on average to reach a decision, varying with the complexity of the case and how quickly information comes back⁴. You can get updates on your application through your online account¹⁷.

If you are buying a property, a separate step follows: a Co-Ownership property assessment report is usually available in the Documents section of your online account within seven working days of uploading your property details⁶.

How long the whole process takes

Two timelines matter, and they are different lengths.

From application to completion, Co-Ownership says most applications take between three and six months, although this can vary depending on the case¹⁸. From accepted offer to completion, the typical figure is 8 to 12 weeks, which Co-Ownership describes as similar to any house purchase⁷.

The gap between the two figures is the property search. The approval window, 4 months for Co-Own, is the period in which you need to find a home and have an offer accepted⁶. Once you have an accepted offer, the 8 to 12 week completion period runs alongside the ordinary conveyancing work that any purchase involves.

For comparison, an equity release application to completion is typically within a week or two if everything is straightforward and the solicitor has sent the bundle of signed documents²⁰. That is a different product with a different process, but it shows how much of the Co-Ownership timeline is the property purchase itself rather than the scheme's own administration.

If something goes wrong

The documents stage is where most applications stall, and the usual causes are predictable: an identity document that does not match Co-Ownership's accepted list, a missing bank statement for an account you had forgotten about, or income evidence that does not cover every job.

If you are struggling with debt or arrears while applying, free and impartial help exists. StepChange, Age UK and Business Debtline all provide debt advice, and debt advisers commonly ask for bank statements for the past 3 months as a starting point²¹. If you own your home with a mortgage and are having trouble paying, you may be able to apply for a Support for Mortgage Interest Loan for help with the mortgage interest²². The Home Owners' Support Fund schemes require you to complete an application form with the help of an approved money adviser and provide a letter confirming that you have taken independent money advice²³.

If you are on Universal Credit or another benefit, note that savings and capital can affect what you receive, and there are rules on deprivation of capital if money has been given away or spent down before a claim¹⁵. A Discretionary Housing Payment claim usually requires your most recent payslip, bank statements covering the last two months, proof of any loan, credit card or hire purchase repayments, and letters from your landlord about rent arrears²⁴.

For the application itself, Co-Ownership's help centre covers proof of income, supporting documents and bank statement requirements, and your online account is where updates appear¹⁷.
