What is a property co-ownership agreement?
When two people buy property together, the deed usually says only that they both own it. It rarely says who put in more of the deposit, how the mortgage is split, who can live there, or what happens if one wants to sell and the other doesn't. A co-ownership agreement fills that gap before it becomes a dispute.
This template records each owner's percentage share and contributions, how mortgage payments and running costs are shared (by share, equally or your own split), how overpayments are settled, who uses the property and on what terms, urgent repairs one owner may order alone, a buy-out process with an independent valuation and deadlines, a sale if no buyout happens, an optional lock-in date, what happens on death, and mediation before court. It is explicit that it does not change how the title is registered — so you can pair it with the formal documents your local law needs.

Using the property co-ownership agreement, step by step
1 Record the shares and contributions
Enter the purchase price, what each owner put towards the deposit and costs, and each owner's percentage share. The shares should add up to 100. Add how the title is held (for example as tenants in common) if you know.
2 Agree costs and use
Choose whether the mortgage and running costs are split by share, equally, or in a way you describe. Add the joint account you'll pay from, and describe who lives at the property — including any rent an occupying owner pays the other.
3 Set the exit rules
Choose how long the other owner has to decide on a buyout of a leaving owner, and how long to complete it. Add an optional date before which neither of you will force a sale, and the urgent-repair limit either owner can spend alone.
4 Take advice and sign
Both owners should read it carefully and ideally take independent legal advice, then sign online. VergeHR places both signatures and initials on every page and files the signed copy in Files.
Tips Before You Send It
- Your lender can usually pursue either of you for the whole mortgage, whatever your agreement says about sharing it.
- How the title is held (for example joint tenancy versus tenancy in common) can decide what happens to a share on death. Check it and make wills that match.
- In some places a declaration of trust or a registered document is needed for unequal shares to be recognised. This agreement doesn't replace it.
- Keep receipts for major improvements and record in writing whether the payer gets that money back first on a sale.

Property co-ownership agreement: frequently asked questions
Does this agreement change who owns the property?
No. It records how the owners have agreed to share the property between themselves. It does not change the registered title, and transferring or registering an interest in land usually needs a separate formal document under local law.
What happens if one owner wants to sell and the other doesn't?
The owner who wants to leave gives written notice. The value is agreed or set by an independent valuer, and the other owner can buy them out within the time you set. If they don't, the property is sold and the proceeds split by share.
What if one owner stops paying their share?
The other can pay it and ask for it back. Anything not repaid is a debt that can be taken from the non-paying owner's share when the property is sold or bought out.
Can this be signed electronically?
Yes, for the agreement itself — electronic signatures are generally valid for ordinary contracts in the US (ESIGN Act and UETA), the UK, the EU (eIDAS) and Canada. Deeds, transfers of land and documents that must be witnessed or notarised often still need wet ink or a specific process, so check before using an e-signature for those.
Is this template free?
Yes. The template is free to use with the eSignature app in VergeHR. The other party doesn't need a VergeHR login to sign.
