No matter what arrangement was made regarding your pet before, during, or after a breakup or the end of a pet-watching situation, our animal attorneys have the experience and knowledge you need to keep your pet safe or get your pet back from a vengeful ex-partner, family member, or former friend.


Kristina is an excellent attorney. She was extremely dedicated to my case. She gave me the strength and confidence to continue my battle for custody of my dog. I cannot say enough good qualities about her. I highly recommend her.

In a day and age where everybody seems to be fighting and there’s conflict everywhere, Kristina Bergsten brings a calm, experience to any situation. I hired her because I was being sued by my ex for the custody of our cats. She did not sugarcoat anything or tell me what I wanted to hear, instead, she clearly and kindly explained the law and took a strong stand for me.

If you want a dignified, affordable and experienced attorney, hire Kristina Bergsten!

– Charuta

I was very pleased with the help I received from Kristina Bergsten for my situation. She communicated with me well, during the time between court and was confident in her approaches. The judge even mentioned that I had good representation. My situation was over by pretrial as she was able to talk the DA into something I agreed on.
