Coming across a Stipulation of Interests may come across as a daunting task. However, Tracts make it easy to input, track, and maintain these types of documents.
In short, you will need to create a new instrument that has the parties involved with the stipulation listed as both the grantors and grantees. When the parties are all listed as grantors, each party's interest is combined together. When the parties are listed as grantees, in this situation, each party has an equal 1/3 interest in the surface and bundle of sticks. The interests divided come from the total interests the grantor parties have before this document is entered.
