Bolton Abbey is not far from Skipton.
Could be he left the lease of the farm? He might have held it for "three lives" (his own, a son and grandson perhaps) and have left the remaining lease to someone else, perhaps a second grandson? I think that was possible.
This is the exact wording on the will: "Item I will that my son Martin with the Leave of the Lord and Owner thereof have the farm where I now dwell."
Leave of the Lord Might also mean the property was
Copyhold meaning that the Manor Court dealt with the Transfer, rather than the appropriate Yorkshire Deeds Registry (which survive from the early 1700s).
When my family were transferring Copyhold property we owned, my family would instruct a Solicitor to:-
1) approach The Manor Land Agent / Estate Office and get a valuation a % of the property value to be Admitted to the Manor.
2) Pay the Admission and get a Manor Court date.
3) Attend the Manor Court and while the Transfer and Admission took place, hold a straw in your hand if it was the Custom of that Manor (it was for us).
4) The Transfer was then entered in the Manor Court Rolls and The Admissions Book.
Quite a lot of Manor Court Rolls survive in Archives, University Special Collections and some have been found in the British Library Dept Manuscripts and places like that.
Some straws that people held in the Manor Court were affixed to the Transfer admission document and sometimes in Archive Collections you will see a description and it says ...
with Straw attached or similar wording.
The Manor Court documents, are more likely to give more information about the exact type of Tenure and Transfer.
Mark
Added: Some Rented / Leased Manor property could also transferred from one family member to another. Let for a specific Term of Years.
Surviving Manor Rolls (Manor Court Rolls), Survey, Rentals can sometimes be really useful to the Family Historian and House researcher and give a clue to the exact type of Tenure and situation.

When the Manor sold our village pub in 1766, the first owners had to pay a
Quit Rent for 35 years according to the Rental Books.
It was also noticed at another Archive (which also held some Manor MSS for 1764 - 1765) that the Pub Licensee had sat on the Manor Court, describing him as
Owing Suit to the Court and naming him.
