What to do if 2 people own a house but one owner refuses to pay property taxes?

If one owner refuses to pay property taxes, the other owner should first communicate with them to discuss the issue and seek a resolution. If that fails, the paying owner may need to cover the taxes to avoid penalties or foreclosure, and then seek reimbursement from the other owner. Additionally, consulting a legal professional can provide guidance on potential actions, such as filing a partition action to resolve ownership disputes. It's crucial to document all communications and payments related to the property taxes.
