Thanks for clarifying!
A girlfriend/boyfriend is not typically entitled to her/his significant other's assets upon his/her passing unless a will granted items to her/him.
Accordingly, a significant other is not typically entitled to remove items from a deceased person's home, even when they lived together as a couple.
In some instances, doing so could constitute a crime.
If law enforcement will not pursue such a matter, an individual may wish to discuss the matter with supervisors at the local law enforcement agency or the individual may wish to discuss the matter with the prosecutor's office. Either option can potentially be helpful in getting the state to pursue a matter.
Regardless of the state's action, an affected individual or the estate may have a basis to file suit against a significant other who takes property that isn't hers/his.
The plaintiff may also be eligible to recover court
costs and attorney's fees if successful.
I know that this probably isn't entirely what you wanted to hear. However, it's the honest truth and I know you want a truthful answer above all. I hope that you will click accept so that I am paid for my time and effort spent providing this information.
