If the Grantor is the equitable/legal title holder of the asset, it may be granted into the Trust (without a necessity for probate). No matter the asset, it can be granted into the Trust's ownership. Passing assets to heirs can be done by a beneficiary-model (open to public scrutiny) OR as a passage of Trust control (private). Further, the asset can be sold by the Trust at any moment to whomever it sees fit (save a Trustee - requiring third-party verification for due consideration on sale). Notice that it is best to be indigent, leaving the trust to own everything.
A Trustee cannot "grant" assets into the Trust Res freely, it must occur be by sale (taxable event of private credit), exchange via Private Security Agreement (barter) and/or Capital Interest Certificate (bond). When using a Capital Interest Certificate to make an exchange of property into the trust res, put "[FULL NAME] Exchanged $XX,XXX for XX Capital Interest Certificate(s)" in trust minutes. There is no need to print the Capital Interest Certificates until it is time to vest the trust or if an investor asks for it. There is an unlimited amount of Capital Interest Certificates that can be made, it is up to each individual to decide how many certificates to issue based on each item exchanged. Be aware that the certificates have no par value and therefore cannot contain a guarantee to trade at any specific amount (e.g. 1 CIC = 1 Oz of Silver or $100). However, the decision to exchange a "$100 or a car" for 1 certificate is left up to the Board of Trustees and their discretion.
NOTE: If an asset is owned between multiple parties, the name can be changed into the name of the trust without approval (unless a previously signed contract limits this ability). There may be additional steps needed like changing the owner's name with the Clerk of Court of Secretary of State. This will officially change ownership.
