Answer a few questions
Did the person own property or land in their sole name — or a share as tenants in common?
Why these three questions settle it
Probate exists to unlock sole-name assets. Everything that passes another way — survivorship on joint accounts and joint-tenant property, nominations on pensions and trust-written life insurance — never enters the estate at all. What's left is sole-name money, and for that each institution decides whether its own threshold is exceeded. The full reasoning, including the tenants-in-common trap, is in do I need probate?
If the answer is yes
Don't panic and don't pay anyone yet. Straightforward estates are administered by ordinary people every day: the online application plus the HMRC forms is genuinely manageable, and the court fee is £526 for estates over £5,000. Read the probate guide, budget with probate costs and the fees estimator, and work the executor checklist in order.
