TLDR

ILA stands for Independent Legal Advice.

In mortgage and property transactions, ILA is usually required when someone is taking on a legal or financial responsibility and needs to understand the risks before signing.

This often applies in cases such as:

Joint Borrower Sole Proprietor mortgages
Personal guarantees
Company or SPV buy-to-let mortgages
Occupier consent forms
Family-assisted mortgages
Some gifted deposit or transfer of equity situations

The purpose of ILA is simple: to make sure the person signing understands the legal risks, obligations and possible consequences before they commit.

What Does ILA Mean?

Independent Legal Advice means advice given by a solicitor or qualified legal adviser who is independent from the main transaction.

The solicitor’s role is to explain the document, the legal responsibilities, the risks involved, and what could happen if things go wrong.

In many cases, the solicitor will also sign an Independent Legal Advice Certificate confirming that advice has been provided.

In simple terms: ILA is there to make sure you know exactly what you are signing.

Why Do Mortgage Lenders Ask for ILA?

Mortgage lenders ask for ILA because they want to make sure everyone involved understands their responsibilities.

This is especially important where a person may be liable for a mortgage or loan but may not fully benefit from the property or borrowing.

UK Finance’s Mortgage Lenders’ Handbook notes that ILA may be required where a borrower will not also be a proprietor of the property, or where part of the loan is not for the benefit of all joint borrowers.

Who it protects	How it helps
The person signing	They understand the risks before agreeing.
The lender	It reduces the risk of someone later saying they did not understand the document.
The main borrower	It helps the mortgage process move forward correctly.
The solicitor	It creates a record that advice was given.

When Is ILA Commonly Needed?

Situation	Why ILA may be needed
Joint Borrower Sole Proprietor mortgage	A person may be responsible for the mortgage but not own the property.
Personal guarantee	A director or individual may become personally liable if a company cannot repay a loan.
SPV or limited company buy-to-let	Directors or shareholders may need advice before signing guarantees.
Occupier consent	An adult living in the property may need to confirm they understand the lender’s rights.
Family-assisted mortgage	A parent or family member may need to understand their legal position.
Transfer of equity	One person may be added to or removed from the property ownership.

How Much Does ILA Cost?

The cost of ILA depends on the solicitor, the type of document, the lender’s requirements, the level of risk, and whether more than one person needs advice.

As a broad guide, many UK solicitors advertise ILA fees from around £120 to £300 plus VAT, while more complex cases or additional borrowers may cost more.

Is ILA the Same as Mortgage Advice?

No. ILA is not the same as mortgage advice.

A mortgage adviser helps you understand the mortgage product, lender criteria, affordability and application process.

A solicitor providing ILA explains the legal risks of the document you are signing.

Mortgage adviser	ILA solicitor
Advises on mortgage options	Advises on legal documents and risks
Helps with lender criteria	Explains your legal obligations
Supports the mortgage application	May sign an ILA certificate
Looks at affordability and suitability	Checks you understand what you are signing

What Documents Might Be Needed for ILA?

The solicitor may ask for:

Mortgage offer
Loan agreement
Guarantee document
Occupier consent form
Details of the borrower
Property details
Proof of ID
Details of the solicitor acting on the main transaction

The exact requirements can vary depending on the lender, solicitor and type of transaction.
