TL;DR
In short
- In England and Wales, ask your conveyancer to explain the title, searches, easements and covenants before exchange; keep the report on title and relevant correspondence.
- A leasehold is a time-limited interest governed by its lease. Ground rent and service charges are different, and buying an older lease does not by itself make its ground rent a peppercorn.
- Property ownership, inheritance and mortgage debt are separate questions. Joint borrowers are usually each responsible for the whole mortgage debt.
- Raise a legal-service concern with the firm in writing first. Eligible England and Wales service complaints may then be suitable for the Legal Ombudsman; negligence and legal loss need separate advice.
Mortgage problems can arise while you are applying for finance, after a mortgage offer, or after completion. This article covers legal issues connected with the property and ownership rather than the mortgage application itself. The detailed property examples and complaint route below are primarily for England and Wales. Scotland and Northern Ireland have different property systems and legal-service complaint routes.
This is general information, not legal advice. A suitably qualified legal adviser can assess a title, lease or dispute. A mortgage adviser can discuss borrowing options, but does not provide legal advice.

Legal issues after a mortgage offer or completion
Conveyancing is the legal process of transferring ownership. A solicitor or licensed conveyancer reviews the legal title, searches and enquiries. That work is different from a lender’s valuation, which is for the lender, and a condition survey, which considers the property’s physical condition. In the ordinary buying process in England and Wales, exchange is the stage at which the contract becomes binding.
Problems may be found before exchange, after a mortgage offer, or only after completion. The appropriate next step depends on the documents, timing and the advice you received. Choose a properly regulated adviser with relevant experience, a clear scope of work and clear fees; this does not guarantee an outcome.
Title checks, covenants and next steps
The title register records ownership and relevant rights or interests. Title plans normally show general boundaries rather than every exact boundary. A covenant may restrict how land is used, while an easement such as a right of way gives a person a legal right of access; it does not automatically transfer ownership of the land.
For example, a restrictive covenant may limit the construction of an outbuilding or fence. Whether it is enforceable, whether consent is available and what remedy might apply require legal advice. It is not enough to assume that a title record can simply be amended.
If an issue seems to have been missed before exchange, ask the conveyancer to explain it, resolve it where possible, and set out the implications before you commit. After exchange or completion, seek prompt independent legal advice. Keep the report on title, relevant correspondence and documents. A possible failure in the conveyancing work does not, by itself, prove negligence or entitlement to compensation or another remedy.

Complaints and redress for legal services
For an England and Wales legal-service concern, raise it with the firm in writing and keep copies of the response. For an eligible service complaint, you can consider the Legal Ombudsman guidance after the firm’s final response or after eight weeks without a resolution.
Normally, a complaint must be referred within one year of the act or omission, or when you should reasonably have known about it, and within six months of a compliant final response. Eligibility, exceptions and the Ombudsman’s discretion apply, so check the current scheme rules before relying on those time limits.
A poor-service complaint is different from reporting professional conduct to a regulator and different again from a negligence claim for legal loss. The Legal Ombudsman may offer a remedy in an eligible case, but it is not your lawyer and compensation or recovery is not assured. Independent legal advice can help you assess a potential negligence claim.
In Scotland, legal-service complaints are handled through the Scottish Legal Complaints Commission after the firm’s process. In Northern Ireland, solicitor service complaints can be escalated to the Solicitors Complaints Committee after the in-house process; professional-conduct concerns have a different route.

Leasehold charges and management disputes
In England and Wales, a leaseholder owns a time-limited leasehold interest, subject to the lease; the freehold is a separate interest. The remaining term, payment obligations and the way the building is managed can matter, so check the lease rather than assuming that every leasehold arrangement works the same way.
Ground rent is a payment under the lease and is separate from service charges for services, repairs or management. The Leasehold Reform (Ground Rent) Act 2022 guidance generally restricts ground rent to a peppercorn for qualifying new residential long leases granted on or after 30 June 2022, with retirement leases covered from 1 April 2023. Exceptions apply. Purchasing an existing older lease now does not itself change its ground rent to a peppercorn.
Service charges depend on the lease. Costs and work generally need to meet reasonableness standards, and leaseholders may have rights to request a summary and supporting information. Check the lease, demands and accounts, make a written challenge, and take advice before withholding any payment.
For an eligible leasehold dispute, England uses the First-tier Tribunal (Property Chamber); Wales has the Leasehold Valuation Tribunal. The Right to Manage is a collective statutory process with eligibility, company and notice requirements. It can transfer management without the landlord’s agreement in qualifying cases, but it does not transfer the freehold or automatically resolve an individual bill dispute.

Joint ownership, death and separation
Joint ownership, inheritance and mortgage borrowing are related but separate issues. A person can be a borrower, a legal owner, a beneficial owner, or more than one of these; succession questions can arise even without a joint mortgage.
In England and Wales, beneficial joint tenants have survivorship, so the property passes to the surviving owner. Tenants in common have distinct shares, with no automatic survivorship; a deceased owner’s share passes under a will or intestacy rules. A declaration of trust can record beneficial shares and contributions. Discuss whether it is suitable alongside a will and the ownership arrangements; it does not replace a will or determine every outcome on death or divorce.
When a co-owner dies
Check the ownership arrangement, the title and any declaration of trust, as well as the will or intestacy position. The surviving co-owner’s position depends on those facts. Prompt legal advice can help the people dealing with the estate understand their options.

Divorce or separation
After separation, joint borrowers generally remain liable for the whole mortgage debt, and the lender may seek payment from either borrower. A private agreement about payments or a change in ownership does not itself release a borrower. Contact the lender about a proposed transfer or release, which remains subject to its assessment. If payments are missed, act quickly using guidance on missed mortgage instalments and seek legal advice about the property arrangements. Our guide to UK mortgage and divorce explains some practical mortgage options.
Next steps
If you identify a property-law issue, gather the title, lease, report on title, demands and correspondence, then take advice from a suitably qualified legal adviser. For a mortgage concern, a mortgage adviser can discuss borrowing options through the contact form. The right complaint or dispute route depends on the service, jurisdiction, documents and timing.
FAQ
Frequently asked questions
What should I do if I think my conveyancer made an error?
Keep the report on title, correspondence and relevant documents. Before exchange, ask the conveyancer to explain or resolve the issue and its implications before committing. After exchange or completion, seek prompt independent legal advice. A service complaint and a negligence claim are different routes, and neither outcome is automatic.
Does an older lease become rent-free when I buy it?
No. In England and Wales, the 2022 ground-rent rules generally apply to qualifying new residential long leases granted from the relevant commencement dates, subject to exceptions. Buying an existing older lease does not itself turn its ground rent into a peppercorn.
How can I challenge service charges?
Check the lease, demands and accounts, and make a written challenge. Leaseholders may have rights to a summary and supporting information, while costs and work generally need to be reasonable. In eligible cases, the route differs between England’s First-tier Tribunal and Wales’s Leasehold Valuation Tribunal; take advice before withholding payment.
What happens to a jointly owned home when a co-owner dies?
In England and Wales, beneficial joint tenants have survivorship, whereas a tenant in common’s share passes under a will or intestacy rules. The title, ownership arrangement and any declaration of trust matter, so legal advice is appropriate for the particular estate.
Does separation end joint mortgage liability?
Usually not. Joint borrowers generally remain liable for the whole mortgage debt, and the lender may seek payment from either. A private agreement or ownership change does not itself release a borrower; any transfer or release is subject to the lender’s assessment.
