the peace secured between the english and scottish kings did not lead to alan's speedily return to business south of the border. contributing factors to alan's tardiness in english affairs were likely the death of his mother in june 1217, and his subsequent succession to the morville inheritance of lauderdale and cunningham, substantial territorial blocks within the scottish realm. in fact, alan does not appear to have enjoyed the same amiable relationship with henry's regime as he had during john's administration, and it wasn't until 1220 that matters concerning alan's fealty to henry, and the confirmation of alan's english and irish estates were finally settled. in april of that year, correspondence was sent on behalf of alan to henry explaining that alan and his brother were unable to make use of their ulster lands. the english crown thereupon ordered that alan's lands were to restored to him, with a directive to that effect issued to geoffrey de marisco, justiciar of ireland, and a request for alan to attend the upcoming summit between alexander and henry at york. consequently, in june, alan rendered homage to henry at the aforementioned assembly, where he duly received confirmation of his english and irish possessions, and was one of the twelve scottish magnates who swore to uphold alexander's oath that the latter would marry one of henry's sisters, either joan or isabella.
