Answer: The original seller, because her contract obligations as to title merged into the deed
Step-by-step explanation:
A Marketable title simply means a title which is free from any sort of threat of litigation or reasonable doubt. In a situation whereby a clear title of deed cannot be produced to a property, in a specific performance action, the prospective buyer might be expected to lose.
Based on the scenario explained, the original seller, will likely to prevail on this count because her contract obligations as to title merged into the deed.
