I'm a little unsure about how this system works, and of course, being cheap/frugal/ whatever, I hate to waste money.  So my question is this.  I get an invoice from the title insurance company that lists the cost for an owners policy and a sellers policy.  In my area at least, sellers pay both.  So it's about 1k.  But my question is, when I bought the house a few months ago, I bought title insurance as owner.  Now that a buyer is using a different company, they have a charge to "reissue owner's policy".  Do I need to buy title insurance to protect me as a seller?.  Or is this just a company trying to sell me their product?  At nearly 500 bucks, I don't need two policies that do the same thing.  Or do I?  Maybe the first owner's policy expires upon sale, and the sellers policy continues to protect me?  

if this seems muddled, I'm now the seller.  But buying title insurance to cover me as seller and the buyer
