Best Time to Instruct a Solicitor for a House Purchase

At Towerstone, we provide specialist property accountancy services for homeowners, landlords, and property investors. This article explains the key points you need to understand around this topic.

Knowing when to instruct a solicitor is one of the most important but most misunderstood parts of buying a house. Many buyers delay because they want to save money, avoid pressure, or wait until they feel the purchase is certain. Others rush to instruct a solicitor too early and then worry about fees if the sale falls through.

The reality is that timing your solicitor instruction correctly can save weeks, reduce stress, and significantly lower the risk of the purchase collapsing. In my experience, many of the delays and problems buyers face are not caused by bad luck but by instructing a solicitor too late.

In this guide, I will explain clearly and practically when you should instruct a solicitor when buying a house in the UK, why timing matters so much, what happens if you instruct too early or too late, and how to handle fees sensibly. By the end, you should know exactly what to do and when to do it.

The short answer most buyers need

In most cases, you should instruct a solicitor immediately after your offer is accepted.

That is the safest and most efficient point for the majority of buyers.

However, there are situations where it makes sense to line a solicitor up before you make an offer, and situations where delaying instruction causes unnecessary problems. Understanding the difference is key.

What instructing a solicitor actually means

Instructing a solicitor does not mean you are legally committing to buy the house.

It simply means you are formally appointing a solicitor or licensed conveyancer to act for you if the purchase proceeds. They will open a file, carry out identity checks, and be ready to start work as soon as the seller’s solicitor issues the contract pack.

You are not exchanging contracts and you are not locked into the purchase just by instructing a solicitor.

Why timing matters so much

Property transactions in England and Wales move in stages, and many of those stages can run in parallel if your solicitor is ready.

When buyers delay instructing a solicitor, several things happen:

The seller’s solicitor issues the contract pack but there is nobody ready to receive or review it
Searches are delayed because there is no solicitor authorised to order them
Legal enquiries start later than necessary
The seller may lose confidence in the buyer’s seriousness

All of this pushes the timeline back and increases the risk of the seller accepting another offer or the chain collapsing.

The ideal timeline for instructing a solicitor

The most efficient and widely recommended timeline looks like this.

Before you start viewing properties, you research solicitors and decide who you would like to use. You may request quotes and confirm availability but do not formally instruct yet.

Once your offer is accepted, you immediately instruct your chosen solicitor. This allows them to open the file, carry out ID checks, and request search fees straight away.

While your mortgage application and survey are being arranged, your solicitor can already be working in the background.

This overlap is what keeps transactions moving.

Should you instruct a solicitor before making an offer?

In some situations, yes.

Instructing a solicitor in principle before making an offer can be helpful if you are:

A first time buyer who wants guidance early
Buying at auction where legal review is needed before bidding
Buying a complex property such as a flying freehold or leasehold with known issues
In a very competitive market where speed matters

In these cases, having a solicitor already lined up means you can move instantly once an offer is accepted.

However, fully instructing and paying upfront before any offer is agreed can be unnecessary if you are still viewing widely and unsure which property you will buy.

Why instructing too late causes delays

Many buyers wait until after their survey or mortgage offer to instruct a solicitor. This is a mistake.

By the time your survey is complete and your mortgage offer arrives, several weeks may already have passed. If your solicitor is only instructed at that point, legal work starts far later than it should.

This creates a bottleneck where everything else is ready but conveyancing has barely begun. Sellers often become frustrated at this stage and start to question whether the buyer is serious.

Late instruction is one of the most common reasons sales overrun the expected timeframe.

What happens immediately after you instruct a solicitor

Once you instruct a solicitor, several things happen quickly.

They carry out identity and anti money laundering checks. They request money on account for searches. They notify the seller’s solicitor that they are acting for you. They prepare to review the contract pack as soon as it arrives.

None of this commits you to buying the property, but it removes friction from the process.

How solicitor instruction fits with mortgage applications

Your solicitor and mortgage lender work in parallel.

While your lender is assessing affordability and arranging a valuation, your solicitor is dealing with legal checks, searches, and enquiries.

If you delay instructing a solicitor until the mortgage offer is issued, you lose this overlap and extend the overall timeline.

Mortgage lenders also expect buyers to have legal representation in place early. Delays can cause frustration for brokers and underwriters.

Searches and why early instruction matters

Property searches are one of the slowest parts of the buying process.

Your solicitor cannot order searches until they are formally instructed and have received funds for search fees. In some areas, local authority searches can take several weeks.

Ordering searches early can save a huge amount of time later. Delaying solicitor instruction delays searches and pushes everything back.

What if the purchase falls through?

This is the main reason buyers hesitate to instruct solicitors early.

It is true that if the purchase falls through, you may still owe some fees. However, most solicitors charge in stages, not all at once.

In many cases, if a purchase falls through early, costs are limited to ID checks and perhaps search fees if searches were ordered.

Some solicitors offer no completion no fee arrangements, although you should always check what is and is not covered.

The cost of instructing early is usually far lower than the cost of delays or losing the property due to slow progress.

How sellers view solicitor instruction

From a seller’s perspective, early solicitor instruction is a sign of seriousness.

Estate agents often ask buyers whether they have instructed a solicitor when an offer is accepted. Buyers who say yes are often viewed more favourably than buyers who say they will do it later.

This perception can matter, especially if there are competing offers or if the seller is nervous about the chain.

Leasehold purchases and early instruction

If you are buying a leasehold property, early solicitor instruction is even more important.

Leasehold transactions involve additional documents such as management packs, service charge accounts, and freeholder information. These often take time to obtain.

The earlier your solicitor is instructed, the sooner these requests can be made.

Leasehold delays are common, and late instruction makes them worse.

Cash buyers and solicitor timing

Cash buyers sometimes assume they can delay legal work because there is no mortgage involved.

In reality, cash buyers benefit just as much from early instruction. Searches, title checks, and enquiries are still required. There is no lender safety net, so your solicitor is the only person protecting you.

Cash buyers who instruct solicitors late often lose their main advantage, which is speed.

Auctions and new builds

Auction purchases are a special case.

If you are buying at auction, you should instruct a solicitor before bidding. Auction contracts become legally binding immediately, so legal review must happen in advance.

For new build properties, developers often push for quick exchange. Having a solicitor instructed early avoids panic and rushed decisions under pressure.

What happens if you instruct the wrong solicitor?

Another concern buyers have is choosing the wrong solicitor too early.

The solution is preparation. Before making any offer, research solicitors, read reviews, check communication style, and confirm experience with your type of purchase.

Switching solicitors mid transaction is possible but it causes delays and additional cost. Choosing carefully at the start avoids this problem.

How to choose a solicitor before you need one

A good approach is to shortlist one or two solicitors before you even make an offer.

Ask about fees, communication methods, experience with leasehold or complex properties, and expected turnaround times.

That way, when your offer is accepted, you can instruct immediately without scrambling to find someone.

Common myths about instructing solicitors

One common myth is that instructing a solicitor locks you into the purchase. It does not.

Another is that solicitors cannot do anything until the mortgage offer arrives. They can and they should.

A third myth is that delaying instruction saves money. In reality, it often costs more in the long run.

When delaying instruction might make sense

There are limited situations where delaying full instruction is reasonable.

If you are still negotiating an offer and nothing is agreed, or if the seller has not formally accepted your offer, it may be sensible to wait.

If you are viewing multiple properties and unsure which you will buy, you may prefer to line a solicitor up rather than instruct fully.

Once an offer is accepted, delay rarely helps.

How early is too early?

Instructing a solicitor months before any offer is agreed can be unnecessary unless you need specific advice.

However, being prepared and ready to instruct is never too early.

The key difference is between preparation and formal instruction.

The cost versus benefit balance

Solicitor fees are small compared to the cost of buying a house and the risk of something going wrong legally.

Early instruction increases the chance of a smooth transaction, protects your position, and keeps momentum.

In most cases, the benefit outweighs the small risk of abortive costs.

What experienced buyers do

Experienced buyers almost always instruct solicitors as soon as an offer is accepted.

They understand that conveyancing is a bottleneck, not a formality, and that delays increase risk.

This is one of the biggest differences between smooth purchases and stressful ones.

Final thoughts

For most buyers, the right time to instruct a solicitor is immediately after your offer is accepted. This allows legal work, searches, and enquiries to start early and run alongside your mortgage and survey.

Waiting until later rarely saves money and often costs time, confidence, and sometimes the property itself.

In my experience, buyers who instruct solicitors promptly feel more in control, encounter fewer delays, and are far less likely to see a transaction drift or collapse unnecessarily.

Buying a house is complex enough without avoidable delays. Getting the timing right on solicitor instruction is one of the simplest ways to make the process smoother from the very beginning.
