Save for some religious engagements, the press ceased to mention his name. In the early 1940s Valiente decided to re-launch his academic career and served as auxiliar temporal at the Law Faculty in Madrid. In 1942 he entered the selection process for the post of chair of Civil Law and in 1943 was nominated catedrático numerario in the Universidad de La Laguna in the Canary Islands. In early 1946 he applied for transfer to the parallel position in Universidad de Sevilla; however, when admitted he agreed a swop with Miguel Royo Martínez from Zaragoza. He moved to Aragón, but did not complete the full annual academic cycle. In 1947 Valiente requested unpaid leave. The same year he vacated the post, though formally he remained related to the Zaragoza University; he went on practicing as a lawyer. Until 1942, when Franco ignored Don Javier's proposal of forming a Carlist-Francoist government, Valiente seemed to hope for a compromise. In 1939 he co-signed Manifestación de los Ideales, a documented addressed to Franco which urged implementation of Traditionalist features; in 1943 he co-signed another one, Reclamación de Poder, this time explicitly referring to instauration of the traditionalist monarchy. In 1945 he attended a grand Carlist anti-Francoist demonstration in Pamplona and delivered an address from the balcony; afterwards he was detained by security and expected facing the firing squad; eventually the sanctions adopted were relatively mild, especially compared to the terror employed against the Left.

The latter invited him to join the juanistas, the group notionally loyal to the regency, but pressing the candidacy of Don Juan, the Alfonsist claimant, as the prospective Carlist king. Valiente refused to adhere. In 1947 Valiente took part in the informal meeting of the Carlist executive, the first one since 1937; he was nominated vice-president of re-established Carlist Consejo Nacional, effectively the second-in-command within the organization. Highly skeptical about any would-be dynastical agreement Valiente remained loyal to Don Javier; in 1951 he welcomed the claimant in his Madrid home. However, he became somewhat less enthusiastic in 1952, when Don Javier made declarations generally understood as termination of the regency and assumption of his own claim to the throne. Since the early 1950s at meetings of the Carlist command layer Valiente started to make references about "new
