Bypassing Wards

 Physically cross them. Create a physical charm/spell. Hide it in the house. Wards cannot protect a person if a spell is created and activated there.

Make them accept it. Give a cursed object as a gift or package. 

Break them. Associate their protection with clay or glass. Create a connection using a taglock over a course of weeks. Break the object whenever you feel ready. 

Wait till they leave home.

Bind with something sticky. Certain protections are meant to bounce back.

Curse a specific part. Curse a specific area of their life with as much ill intent and resentment as possible.

Take over the wards. Keep out the things they want and things they need.

Overall, really strong intention would be mostly enough to bypass wards. You may do justice spells to ask the Universe to strip the person of protection and there are certain deities to pray to and rituals to do whenever it comes to strong cursing.
