The Gama Lobo Xavier, Luis Teixeira e Melo e Associados law firm was informally created in Guimarães in January of 1978 and was incorporated in May 1989 by the partners Gama Lobo Xavier and Luís Teixeira e Melo.

Its genesis embodies a long and profound professional and personal relationship between the two founding partners, which began in the second half of 1971, which extended and deepened to their direct descendants and, gradually but surely, opened to new partners and associates.
