Can my spouse kick me out over an argument if I'm not on the lease?

If you pay any portion of the rent, then you could be considered a some lessee of hers so that she has to give you a 60 day notice and then sue for unlawful detainer and eviction. You might be able to make the same argument if you continuously pay for anything that also benefits her, such as the utilities, food, etc. Normally, the police will say it is a family dispute and not get involved. If she accused you of hitting her or threatening her with a weapon, they will come and may arrest you. Instead of having these fights all the time, go to family counseling o decide that the relationship is no longer worth it and leave. Your are not just having the type of arguments married couple have, there is a great of bitterness.
