The partnership will offer Paradigm members a will-writing service provided at a fixed price starting at £100 including VAT.
The will writing and other legal services can be completed by telephone and post.
Redstone Wills is a subsidiary of the Skipton Building Society Group.
Bob Hunt, chief executive of Paradigm Mortgage Services, said: “It’s clear that financial advisers are in the perfect position to recommend wills to their clients, yet too often this appears not to be the case.
“Our relationship with Redstone Wills is designed to do just that by providing a completely professional and user-friendly solution designed with both the intermediary and their clients interests at the fore.
“Not only can this added-value service deliver additional, regular and lucrative income to our introducing intermediaries but through provision of such services users are also generating access to executors, witnesses, guardians, and trustees named in the Will - delivering enhanced client referral options.”
David Livesey, chief executive of Connells Group, said: “When arranging protection for clients, I believe it is essential for advisers to make sure their clients money will go where they want it to in the event of their death.
“Recommending a will is best practice and a will from Redstone Wills has the best credentials. You are often judged by the company you keep and we are very proud of our partnership with Paradigm.”
