If I pay taxes on property that has other heirs can I sell this property without their knowledge?

Generally, if you co-own property with other heirs, you cannot sell it without their knowledge and consent, as all owners have a legal interest in the property. Selling a property typically requires the agreement of all parties involved, unless you have a legal provision or agreement that allows you to do so. Additionally, the other heirs may have rights to the property that cannot be ignored. It's advisable to consult with a legal professional to understand your specific situation and the implications of selling shared property.
