1. Is she entitled to any of my inheritance
No. If you inherited it, then it is your separate property, and does not count as part of the marital estate, under Colorado Revised Statutes Sections 14-10-113.
2. Is she allowed to remove this from our property
Since it is your separate property, the answer is no. The most practical approach would be to go to family court to seek the return of the property under legal separation as a whole.
I hope this helps and clarifies. Please use the SEND button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of THREE OR MORE STARS and then click FINISH to submit that rating, as this is how experts get credit for our time. Rating my answer the bottom two stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
