Can an Engineer Stamp Another Architect's Drawings?
Yes — an engineer can stamp another architect's or designer's drawings, but only after reviewing them thoroughly enough to take professional responsibility for the design. A PE who stamps without reviewing is violating their license obligations, so expect a real review process, not a rubber stamp.

Review before seal
Stamping means the engineer certifies the design meets code and is safe — that requires checking calculations, verifying details, and confirming the drawings are complete and buildable. The engineer will mark up anything deficient and require revisions before sealing. This review is what the stamping fee pays for.
What the engineer needs from you
Provide the full drawing set, any calculations behind it, and product or equipment cut sheets where relevant. The cleaner and more complete the package, the faster and cheaper the review. Drawings with unresolved code issues or details the engineer can't verify will come back with required changes — or be declined.
Limits and liability
An engineer generally stamps only the portions within their competence and license — a structural engineer stamps structure, not the electrical design. Some states also have rules about responsible charge, meaning the engineer must have genuine oversight of the work. Be cautious of anyone offering to stamp anything, sight unseen, for a flat pittance.
The bottom line
Yes, with a proper review first — that's both the legal requirement and what protects you. Bring a complete set, expect markup, and avoid anyone who'll seal it without reading it.
