Who writes the calculators

Morgan Leith, editor

Morgan Leith is the pen name of the independent editor who runs LegalSums. Morgan collects the published court, tribunal, probate and Home Office fees and limits, and keeps the calculators in step with them when they change.

Morgan isn't a solicitor or a regulated immigration adviser, and nothing on LegalSums is legal advice.

How the figures are checked

Every fee, limit and scale comes from a published source: a fee order, GOV.UK guidance, a tribunal or Home Office table. Each calculator links to those sources, and the "figures checked" date moves on when they are re-checked.

No solicitor or regulated adviser has reviewed these calculators. If one does, they will be named here and on the pages they checked, with a registration you can look up.
