In the US and probably most if not all common law jurisdictions, this means that all of the siblings enjoy equal rights to the property. There are different kinds of ownerships, including tenancy in common and joint ownership. Whatever the case may be, one or more of the co-owners cannot confiscate your property, so they cannot remove your claim. They also cannot kick you out. The only legal way to remove you is via a court process where, after a court order, the sheriff tosses you into the street. It would be a crime (literally) for them to physically remove you themselves.
They could sue you for your share of the "bills", depending on what those bills are. For example, as a co-owner, you have an obligation to pay a portion of the property taxes, even if you don't live there. You do not have an obligation to pay a portion of the cable bill if you don't live there. You would be liable for a share of necessary repairs, but not unnecessary fancying-up. You would also be entitled to a share of any rant received, in case they had been renting out a part of the house. Since you do in fact owe a share of the taxes and repairs, it is counterproductive to say "Oh yeah? Sue me!".
