Age Concern is collaborating with the Department of Trade & Industry to help spread information to older same-sex couples ahead of the implementation of the Civil Partnerships Act later this year.
The Act - due to come into force on 5 December - will allow same-sex couples to form civil partnerships from 21 December.
Age Concern is planning to distribute the DTI booklets to ensure older same-sex couples are fully informed about the issues raised by the Act, including questions surrounding pensions and next of kin.
The move follows a widening of Age Concern's work in this area over the past few years.
The Age Concern Federation is in the process of building a new network of older lesbian, gay and bisexual (OLGB) development officers.
At present, Age Concern's national OLGB network boasts 46 members, comprising Age Concern groups and other related organisations.
