- I would imagine it should be dukedom. A country ruled by a Duke is a Duchy. A Dukedom is a noble designation. Spanish Dukes are members of the nobility rather than monarchs. 188.8.131.52 (talk) 14:22, 7 December 2012 (UTC)
What happens if the senior heir is underage? Does the 2 year limit apply to them or does it start after they reach majority? Can their guardian apply on their behalf? (Alphaboi867)
Shouldn't it be Marques (or Marquis) instead of Marquess?
Removed text - contradictory and unclear
- Legitimate and natural [Sureley not - natural children (i.e. bastards, are surely excluded!) patrilineal descendants of a nobleman are also noble,
In what sense is "and" used here? Are adopted children noble? (They are not "natural") Are illegitimate children noble? (They are not "legitimate") The editorial inquiry ("Surely not...") belongs in the talk page not in the article.
- as are those female-line descendants whose inheritance of a legal title of nobility is recognized.
The structure of this sentence implies conditions in which the legal title is recognized and conditions where it would not be recognized. This is not explained in the body of the article.
This would be better written as "some female-line descendents are noble" and then explain the conditions for such recognition in the article body.
- In Spain female line descendents are treated just like male descendents. Gender may not be discriminated as one will see in the current guidelines. 
Maqueda and Santangelo?
What about the titles Duke of Maqueda and Duke of Santangelo? According to this Wiki article, those titles are currently held by Luis María Gonzaga de Casanova-Cárdenas y Barón, Duke of Santangelo, son of Balthasar de Casanova-Cárdenas y de Ferrer and María de los Dolores Barón y Osorio de Moscoso, Duchess of Maqueda. However, this article doesn't mention these titles. Surtsicna (talk) 08:23, 7 September 2008 (UTC)
Grande de España
Would the title of Grandee pass on to a holder's children? For instance, when the children of Infanta Cristina get married and have children, would her sons pass on the title to their children?
Divisions of the Spanish peerage?
The UK peerage is divided into several peerages reflective of the constituent kingdom from which they originated. There is the English peerage, Scottish peerage, Irish peerage, then once the formal unification there is the peerage of Great Britain, and now the peerage of the United Kingdom. Does the Spanish nobles/peers follow a simular organizational approach? Are there Leonese-Castillian nobles, Aragonese nobles, then Spanish nobles?♦Drachenfyre♦·Talk 15:51, 6 November 2010 (UTC)
