Legal 500 2026, Personal tax, trusts and probate

Probate and estate planning provide individuals with the structure and clarity needed to protect their assets, support loved ones and plan for the future. Thoughtful estate planning helps ensure that wealth is transferred smoothly and tax‑efficiently, while probate processes settle an estate in accordance with a person’s wishes. Both areas require sensitivity, precision and an understanding of personal and financial priorities.

Estate planning may involve wills, trusts, lifetime gifting, succession strategies and the management of complex asset portfolios. For families with international ties, business ownership or non‑standard financial arrangements, additional considerations may apply. Probate, meanwhile, requires careful administration, from asset valuation and debt settlement to the distribution of an estate.

A clear, structured approach brings peace of mind and reduces the likelihood of disputes. By planning effectively and managing estates with care, individuals ensure that their wishes are respected and their families are supported during times of change.

At Keystone, our lawyers have the expertise to present you with all the options to consider when it comes to planning for your estate or managing probate. Advice on how best to settle affairs appropriately is delivered in a timely, practical, and sensitive manner. We advise on the full range of estate planning services, including making a will, estate administration, establishing a family trust, inheritance tax planning, succession planning, and any other probate-related issues.

Individuals turn to our probate lawyers for advice on will creation, trusts, and estate planning. We also advise the executors of a deceased’s estate whilst identifying any tax or asset-related issues.

Our specialist probate lawyers can help to simplify the complex process of planning effectively for the future as well as dealing with an individual’s estate after their death. The team comprises highly experienced probate lawyers, as well as tax experts to help with any issues relating to taxes.

When it comes to offering contentious trusts and probate advice, our expert lawyers recognise that earlystage involvement and quality advice can be key to conflict avoidance.
