Under No. 7 Certification (2011 standards) is a blue wet ink signature required? Is digital being accepted with recorded "Digital Certificate". Also a seal appears to be required. However, Minnesota, from what little I can find, appears vague on the seal requirement. Are any of these questions decided per state? Thank you.
Some states require a 'wet' signature; ALTA/ACSM does not. There is at least one state (NY) where the law says a survey is not valid unless there is an original signature (in some color of ink, as I recall). ALTA/ACSM do not require an original signature.
I was unaware that any state was vague on use of a seal, but ALTA/ACSM expects one. How it is applied is, again, a function of state law and/or surveyor preference.
The manner and nature of digital delivery is also controlled by state law and/or the individual surveyor's preference. All ALTA/ACSM is saying is that digital delivery of a Land Title Survey is fine with ALTA and NSPS. The same would go with a digital signature - whatever state law proscribes, and the surveyor is comfortable with.
