Hope someone can help I married my partner of 20 years 2 days ago and am now panicking about name change! I know I will have to contact tax credits and tell them even though we have been claiming as a couple for years it shouldn't make any difference or mess things up now we are married wil it? Also do I do that first or contact national insurance or passport or something else that's more important? Also do I have to contact tax credits within 30 days? Getting myself in a right old state here!
