n. 1) In real estate, the right and ability to reach a property. 2) Refers to the opportunity for a husband to engage in sexual intercourse with his wife. This usage, though somewhat crude, is significant because if a husband had access to his wife during the period when she became pregnant, he is presumed to be the father. However, modern advancements in blood tests and DNA studies can reveal the true father, regardless of whether the husband had access or not.
