Question: Beverly signed a form contract to buy a condo from Susan. The Purchase and Sale Agreement had blank lines where the names of the parties, the terms of the sale (such as price, down payment, subsequent payments and description of the property) could be inserted. While the names of the parties and the price were written in the blanks, the payment terms were left blank. Sometime later Beverly and Susan disagreed on the payment terms, dates of payments and length of payments. Beverly accused Susan of breach of contact she sued Susan and tried to introduce oral testimony about the payment terms. Please explain whether the court would allow this oral testimony.
