Can I Add My Significant Other To My Health Insurance? 
Only if you and your significant other are legally married . So , if it is a male/female relationship you are inquiring about then things are pretty straightforward from the marriage standpoint . If it is a same sex relationship you are inquiring about then things get more complicated . Same sex marriage is an issue that is still being addressed on a state by state basis . If your home state does not recognize same sex marriage and your employer is domiciled -LRB- incorporated in , established in -RRB- in such a state then you ca n't get married in that state anyways and an out-of-state marriage in a state that does recognize same sex marriage is not recognized in your home state . There is a tremendous amount of litigation going on in the Federal courts over this issue which makes it hard to be totally definitive when addressing this question . To make things even more interesting , you might work at a branch location of a company domiciled in a state that recognizes same sex marriage while your state of residence still does n't . And your employer 's policy may be to accept same sex spouses as dependents under their group health plan . This can result in the situation where one same sex couple -LRB- you still have to be married but I 've got some neighbors that went out of state to get married in a jurisdiction that does allow for same sex marriage even though our home state currently does not -RRB- may be able to take advantage of their employer 's health coverage while a similar same sex couple across the street who work for employers headquartered in states that do n't recognize same sex marriage ca n't cover their same sex spouse as a dependent . It is an interesting time to be in the employee benefits business .
