On 31 March, the Cabin Boy™ emailed me a copy the official change of address form that submitted to the Circuit Court to advise the Clerk of his Clinton, Iowa, address. On 3 April, I served court papers on the Cabin Boy™ by mail using the address he provided on that form. According to the USPS tracking information for the package, it was put in the Cabin Boy’s™ mailbox on the 5th.
However, on 20 April, the Clinton, Iowa, Post Office processed it for return. I received it back on the 22nd, marked: RETURN TO SENDER. ATTEMPTED—NOT KNOWN. UNABLE TO FORWARD.
Maybe the postman should have looked under the porch.
