Assuming you are in an area where title insurance is customary, an attorney can help review the title search and explain the title exceptions as to what is not insured, and determine whether the legal description is correct and whether there are problems with adjoining owners or prior owners. He or she can also explain the effect of easements and agreements or restrictions imposed by a prior owner, and whether there are any legal restrictions which will impair your ability to sell the property.

The title search does not tell the buyer or seller anything about existing and prospective zoning. A lawyer can explain whether zoning prohibits a two-family home, or whether planned improvements violate zoning ordinances.

The closing is the most important event in the purchase and sale transaction. The deed and other closing papers must be prepared. Title passes from seller to buyer, who pays the balance of the purchase price. Frequently, this balance is paid in part from the proceeds of a mortgage loan. A closing statement should be prepared prior to the closing indicating the debits and credits to the buyer and seller. An attorney is helpful in explaining the nature, amount, and fairness of closing costs. The deed and mortgage instruments are signed, and an attorney can be assure that these documents are appropriately executed and explained to the various parties.

The closing process can be confusing and complex to the buyer and seller. Those present at the closing often include the buyer and seller, their respective attorneys, the title closer (representative of the title company), an attorney for any lending institution, and the real estate broker. There may also be last minute disputes about delivering possession and personal property or the adjustment of various costs, such as fuel and taxes. If you are the only person there without a lawyer, your rights may be at risk.

Perhaps the most important reason to be represented by an attorney is conflicting interests of the parties. Throughout the process, the buyer's and seller's interests can be at odds with each other, and even with those of professionals involved in the sale. The broker generally serves the seller, and the lender is obtained by the buyer. Both want to see the deal go through, since that is how they will get paid. Neither can provide legal counsel. The respective lawyers for the buyer and seller will serve only their own clients' best interests. Seeking the advice of a lawyer is a very good idea from the time you decide to sell or to buy a home until the actual closing.
