Final answer:
DeeAnna is suing for specific performance, a legal action aimed at enforcing the actual performance of a contract when monetary damages are not adequate, specifically in unique transactions like real estate.
Step-by-step explanation:
DeeAnna's decision to take the seller to court to compel the transfer of the title after fulfilling all obligations of a signed contract is an example of suing for specific performance. Specific performance is a legal remedy in contracts where the court orders the party who breached the contract to fulfill their obligations as per the contract terms. This is often used in cases where the subject matter is unique, like real estate, and monetary damages would not be sufficient compensation for the non-breaching party.
