286. Form, and effect, of grants

The grant of any easement under this Chapter shall be effected by an instrument in Form 17a or, in the case of the grant by adjacent proprietors of cross easements of support in respect of any party wall, by an instrument in Form 17b; and the easement shall come into existence on the date on which the instrument is registered.

Any such grant may, so far as the interest of the grantor permits, be either in perpetuity or for any term of years.

There shall be implied in every such grant the grant of all such ancillary rights as may be reasonably necessary for the full and effective enjoyment thereof.

Any such grant may contain an agreement between the proprietors of the dominant and servient lands binding either or both to pay for, or contribute towards, the cost of constructing, maintaining or repairing any way, wall, drain or other installation or work forming the subject matter of the easement.

Any such agreement, and any agreement in a grant for the making of periodic payments by way of consideration therefor, shall be binding on the proprietor by whom it is entered into in respect only of the period during which his proprietorship continues to subsist, and, in respect of any subsequent period, shall be binding on his successor in title for the time being.
