Selling a Jointly Owned Property: Decisions to Agree Before Listing
A shared decision to sell works best when the details are agreed before the first viewing. Set out who owns what, how offers will be approved and what each owner can expect at completion.

Confirm the ownership and the authority to sell
Start with the deed and a current nota simple. Check the owners, shares, mortgages and other rights rather than assuming that equal contributions or a shared loan mean equal legal ownership. Tell the lawyer about any inheritance, separation, usufruct or family-home issue that could affect consent.
For an ordinary voluntary sale of the whole jointly owned home, all owners must consent or be validly represented. A majority share does not by itself authorise selling everybody’s interest. Selling an individual share raises different questions and is not the same transaction.
Agree the price and the offer process
Use a market valuation to discuss an asking price, a private acceptable range and when to review the strategy. Decide how offers will be circulated and how long each owner has to respond. Make clear that silence is not approval.
Consider price alongside finance, deposit terms, included furniture and completion timing. For example, a higher offer with a long delay may suit one owner less than another. Record decisions in a shared written note so the agent receives one consistent instruction.
Set a preparation and marketing budget
Agree which repairs, cleaning and presentation work are worthwhile, who can authorise spending and whether there is a spending limit. Read the agency agreement together, including fees, exclusivity, duration and the circumstances in which payment becomes due.
Keep receipts for agreed expenditure and record whether one owner is advancing money for the others. Paying a bill does not automatically alter ownership shares. Ask an adviser to document any reimbursement or adjustment intended at completion.
Decide how access and occupation will work
If one owner lives in the property, arrange reasonable viewing windows, notice, keys and photography permissions. Decide what can be photographed and where personal items will be stored. Agree how utilities, insurance and routine maintenance will be handled until handover.
Put the proposed move-out date and furniture inventory in writing. Where a tenant, family member or court order affects occupation, obtain advice before promising vacant possession. A marketing instruction does not resolve an existing right to occupy.
Calculate proceeds for each owner
Ask for a completion estimate showing the sale price, mortgage repayment, agreed fees and other deductions, followed by the intended allocation between owners. Confirm the lender’s requirements and distinguish repayment of the loan from cancellation of the registered mortgage charge.
Each owner’s tax position may differ, particularly where residence or acquisition history differs. Ask the tax adviser about individual liabilities and any applicable retention. Do not promise an equal net payment simply because the advertised sale price is shared.
Plan signatures and what happens if agreement breaks down
Confirm who will sign the agency instruction, any deposit agreement and the deed. A contact person needs appropriate authority to sign for another owner. Arrange powers of attorney and identification requirements early if someone cannot attend.
If owners disagree, pause new commitments and explore a negotiated buyout, mediation or legal advice. The Civil Code provides routes to end co-ownership, subject to the circumstances and valid agreements. Court proceedings, costs and outcomes need legal assessment; an agent cannot resolve a deadlock by listing without the required authority.
Make one shared brief before going live
Bring together the agreed asking price, approval process, budget, access arrangements, target dates and legal contacts. Identify any unresolved issue explicitly instead of leaving it for the buyer to discover.
Costa de Oro can provide a valuation and a proposed marketing approach for a jointly owned home in Marbella or the Costa del Sol. The strongest starting point is a brief every owner understands, supported by legal advice where ownership or consent is complex.
Common questions
Can the owner with the biggest share sell the whole home?
A majority share alone is not authority for an ordinary voluntary sale of the entire property. The other owners must consent or be validly represented.
Can one owner handle communication with the agent?
Yes, if everyone agrees. Keep communication authority separate from the legal authority to accept terms or sign for another owner.
What if we disagree about the price?
Compare valuation evidence and each owner’s timing and financial needs. If agreement remains impossible, seek advice on negotiation, a buyout or the legal options before making commitments to buyers.
