Gay consumers could easily misunderstand the new civil partnership law and the financial implications for same sex couples according to Citizens Advice.
The CAB says the law, instated on December 5 this year, is misunderstood as live-in same-sex couples might still be affected even if they do not register their relationship.
The civil partnership law gives gay couples the same legal benefits and tax rights as heterosexual married couples.
The CAB is releasing a guide to the law explaining the legal ramifications, including inheritance, tax, housing and benefits rights.
Citizens Advice head of public information Liz Steward says: We cannot stress enough the importance that same-sex couples are aware of what these changes will mean. Many people do not realise that the changes may affect them regardless of whether they register a civil partnership or not.
