Your questions aren't applicable YET, because the testator is still alive.

You aren't the executor, until the testator dies.

The will could be changed 100 times before the testator dies.

You could predecease the testator, eliminating your ability to perform your duties as executor.

My responses, therefore, are general in nature and should be be construed as legal advice; although I am an attorney, I'm not your attorney and I am unlicensed in Oklahoma.

If two or more people own property, any one of the owners can move to partition the property and the proceeds divided among the owners.

A partition action precludes any owner from barring the sale, if the court so orders said sale.

That doesn't mean that one or more owners can't DELAY the sale by availing themselves of all due process righst accorded to litigants in civil matters.

If six people own property, five can't evict the remaining owner.

They can offer to buy out the owner.

This is the main reason property is often partitioned, owners can't agree.

I suggest you DISMISS any thoughts you may be pondering in question four!!!!
