What does she owe her common-law deadbeat?

She can get a notice of eviction, but she might have to prove that he is an unwanted tenant... hard to do without a lease agreement, but not impossible. A lot of people rent out space in their homes "the old fashioned way" with a handshake.

She will also need a restraining order, but the police must be made aware of the violent past, otherwise they won't give her one.

She also needs to change the locks the second he's gone and get an alarm system installed in the house. Restraining orders are not magic spells and he will probably try to come back. She needs to keep him out and protect herself and if she can't get to a phone, a monitored alarm system will call the police for her.

Someone (probably you and other relatives) need to be there when this is happening, even downstairs or just outside so they have privacy, but still in earshot in case she screams and needs help.

Not sure what the law's are in Canada, but in the U.S. in some states with a relationship of such duration it may require an actual divorce proceeding with a division of the debts and property.

Sounds crazy i know but common law after a certain time period makes it a marriage that requires an actual divorce in some locations around the world.

File notices to evict and get a restraing order against him to where he can't come home...Call police to let them know of the violent nature. Good Luck.

Depends on the canadian law,in australia he would be entitled to a share of everything,house and all

better get legal advise

He's gotta leave the house sooner or later for whatever various reasons they may be. When he does, she needs to rush to change the locks and sling his **** outside.
