What are the circumstances that two or more remaindermen in a life estate can kick out or get rid of another remainderman?

You shared the deed with the parent now their half was left to the other remainderman? This is really a question for a lawyer.

If there are “remainderman” issues, that means there was a Life Estate and the LE had the home / property as an asset of the LE. The LE is the owner not the remainderman. That only changes after the elder dies and a settlement of the LE is done & filed to transfer ownership to each remainderman outside of probate OR of the LE is dissolved while elder is alive with each getting % ownership based on elders age at the time. Their dead, right? So was settlement done?

The tax assessor records and annual tax bill would come addressed c/o in the name of the LE or the new owner(s) if settlement done. How does tax bill read? If it’s only LE then all of you are the future owners.
BUT
if it’s LE and your name, then your % of ownership is determined by how the LE was drawn up and property ownership recorded at the courthouse. To me, this would be an unusual way to do an LE. Most of the time, the elder owns a home 100% and does an LE with a set % to their kids or heirs and it’s done to bypass probate but still keep property taxes low as the elder technically still owns it

Someone drew up the paperwork initially to create the LE and filed it at the courthouse to get to properly recorded. That someone should / would have been an atty as imo LE are not ever DIY projects. I’d suggest that you contact that atty or if they have retired then the firm that took over that practice, to go over settlement of the LE. Find the atty and let them deal with this & work out / negotiate.

Say the LE was dad and 4 kids all equal as per LE, then when dad dies, each kid gets 25% interest in the property. That you lived there and was a caregiver does NOT matter, it’s however the LE was set up as to how after death % ownership is to be done. If 1 refuses to sell and other 3 want it sold, they can force the sale. If the “1” wants to stay living there & keep the home, they need to buy out the others. Others are under no obligation to let you stay there, or pay their share of property bills or expenses, or be willing to get bought out at less than 25% unless there are specific conditions set in the terms of the LE.

I would be very VERY concerned IF because of all this, that the property taxes are not getting paid. While parent was alive the LE was able to keep lower over 65 tax rates & homestead exemption. Once they die all that goes away. Property taxes will go up. Could be a significant $$$ increase, like $600 tax bill becomes $2100. If property taxes r not paid, then high interest & penalty placed each year AND it will be placed on tax sale. Most places have a 3 yr redemption period for tax sales…… so if taxes not paid 3 consecutive years the bidder holding the tax sale certificate can own that house at year 4. If property taxes are not current and you cannot pay them in full, this is a tragedy in the making. Please, pls pls contact the atty and work with the others to do a settlement soon.

Are you and the other remaindermen equally on the deed? Because thats the only way I see a LE working. That the house was turned over to two people with the agreement that the original owner would stay in the house until their death. Then no probate on the house because you both own it.

I don't think being a resident and a caregiver means anything. I would hope that the other person would allow you to stay as long as you paid for the bills and paid taxes. You could buy them out or maybe pay rent to them. I don't see how they could evict u when ur on the deed. Maybe could force a sale. I guess u will just have to see what the other person wants to do. If u aren't agreeable, then u will need a lawyer.
