My girlfriend has been living with me for over six months closer to about a year along with her two older boys, one receives social security benefits because he is a bit disabled, I have been supporting them as well as my dad since he lost his job earlier this year after getting too sick to return to work, since me and my girlfriend are not registered as common law married, how can I claim them so I can get a tax break on the expenses I supported to care for them all?
