- Is the work authentic?
- Does it appear in the artist's catalogue raisonné (if one exists)?
- What is the provenance?
- Is the work looted or stolen?
- What is the condition history? Has the work been lined or otherwise restored?
- Should the work be cleaned?
- Should I have it independently appraised?
- Should I insure it? If so, for how much?
- Do I have a photograph of the work, and know the dimensions and other identifying details, in case the work is stolen?
- If the work is stolen or damaged, do I know what to do?
