IHTM21046 - Household goods and personal goods: valuation and technical issues: settled property
If the deceased had the right to use and enjoy chattels then they would be regarded as having an interest in possession (IHTM16061) in those assets and their value at the date of death should be included in the IHT400 (IHTM10021). This might arise where the deceased occupied their house because they had an interest in possession and they also had a right to use the contents of the house.
