Areas of law reported to the SRA

ImmigrationChildrenCriminalLitigationFamily

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.

Self-reported by the firm in its most recent annual return to the SRA ("the areas of law that the law firm has told us they delivered"). A lagging description of past work, not a live service list, a specialism claim or a quality mark; it may be up to a year old and is blank for newly authorised firms.

The SRA records the firm's constitution as partnership, 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.
