Callistes is a recognised sole practice authorised by the Solicitors Regulation Authority since November 2015 and recorded under SRA number 349307. The SRA record lists 3 practising offices: the head office at 146 Acre Lane, London, SW2 5UT, plus 2 further offices in London. Its constitution is recorded as sole practitioner.
In its most recent annual return the firm told the SRA it delivered work in 8 areas of law: Employment, Landlord and tenant, Family, Litigation, Wills and trusts, Criminal, Non-litigation and Immigration. 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 SW2 5UT falls within Lambeth (London), where the SRA register lists 66 authorised firms with a practising office, 23 of them reporting residential property work. The nearest other SRA-regulated firms by straight-line distance from the head office are Gromyko Amedu Solicitors (same postcode, London), Clapham Law LLP (600 m, London), Clapham Solicitors Limited (600 m, London), Myria Pieri & Co (700 m, London) and Streathers Clapham LLP (700 m, London). 2 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.
