St Albans-based MLP Legal Protection is to become a division of DAS, the legal expenses insurance company.
The move follows negotiations between MLP Holdings AG, the German Financial Institution, and the DAS parent company in the UK.
DAS said there would be no changes to the management structure or personnel within the company and all key functions would be unaffected.
The technical and customer services manager at MLP, Linda Bentley, said: "Due to the sale of the MLP brand in the UK, we have decided to adopt the DAS brand identity for all future activities.
"This enables us to more rapidly implement our business plan which focuses on expanding the product range sold by our brokers and agents."
