Mary-Kate and Ashley are sisters. They owned two adjoining estates in East Hampton, New York. The two estates had originally been one large property, but when Mary-Kate and Ashley bought it in 1990, they decided to split it evenly into two 50 acre parcels. For more than 15 years, Ashley, her employees, and her friends and other guests accessed a lake that they used for swimming in the summer and ice skating in the winter by hopping the short fence that separated the properties and using a pre-existing pathway across Mary-Kate's property. Mary-Kate became embroiled in a messy divorce with her husband Olivier and decided that she no longer wanted to live on the East Coast, and in 2005, she sold the property to her other sister Elizabeth. Elizabeth does not like Ashley, and upon purchasing the estate, Elizabeth had a 10-foot tall brick wall constructed that blocked the pathway.

a. Ashley seeks an injunction to have the wall removed claiming to have an easement by prescription. Will Elizabeth be successful?

b. If the pathway is the only way for Ashley to access the lake, can she make a claim for another type easement? If so, which kind and why?
