Francis Mostyn & Co. Solicitors is a recognised sole practice authorised by the Solicitors Regulation Authority since December 2023 and recorded under SRA number 8005800. The SRA record lists 1 practising office: the head office at 242 High Street, Langley, SL3 8LL. Its constitution is recorded as sole practitioner.
In its most recent annual return the firm told the SRA it delivered work in 5 areas of law: Non-litigation, Criminal, Probate, Wills and trusts and Litigation. Residential property is not among the reported areas, so the firm does not appear in the conveyancing lists on this site's town and city pages.
The head office postcode SL3 8LL falls within Slough (South East), where the SRA register lists 38 authorised firms with a practising office, 16 of them reporting residential property work. The nearest other SRA-regulated firms by straight-line distance from the head office are ARDALE BROWN (formerly Singh Karran & Co) (2.5 km, Buckinghamshire), MYM Law Solicitors LLP (3.0 km, Slough), Jasmine Shergill Solicitors (3.0 km, Slough), Fitz Solicitors Limited (3.3 km, Slough) and Mackenzie & Co (3.3 km, Slough). 4 of those 5 report residential property work.
The SRA records the firm's constitution as sole practitioner, a structure with no Companies House registration, so there is no company record to cross-reference; the SRA authorisation record is the only public register entry for the firm.
