The retention question every fiduciary eventually faces — answered by liability periods, not habit.
There is no single number: it is driven by limitation periods for fiduciary claims, which commonly run for years after discharge or the fiduciary’s death, and can be extended by discovery rules — a beneficiary who only learns of a transaction later may still have a claim. Practical guidance: keep everything for the life of the appointment, plus at least several years after final discharge, and longer for real property transactions and anything involving self-payment. Tax records follow tax rules (commonly seven years); fiduciary records follow liability rules, which are longer.
Whether you die, resign, or are removed, the successor inherits both the role and the audit of your work. Hand over: the full archive, a summary of open items (pending reimbursements, unresolved variances, assets awaiting valuation), and the passwords/credentials list through a secure channel. A clean handover is the last thing that protects you — an archive the successor can audit is your best evidence that there was nothing to find.
Products across the line keep local-first encrypted ledgers with exportable PDFs precisely so the archive survives the appointment: Guardian, POA, SNT, and UK LPA.
Yes — PDFs of statements and scans of receipts are accepted in most proceedings, and some courts now explicitly accept verified electronic statements. Keep backups and be able to produce originals if a specific document is challenged.
A bank line proves payment; an itemised receipt proves what was bought and why. For groceries, utilities, and routine bills, statements usually suffice — for unusual or large transactions, keep the receipt.
Long after: fiduciary claims can be brought by heirs and creditors years later, and limitation periods commonly run from discovery. Several years past discharge is the practical floor; indefinitely for anything involving self-payment is the safe answer.
The principal may demand an accounting at any time while the POA is active — and can revoke it. Keep the same ledger: the person most entitled to see your records is the person who signed the document.
