paragraph_text: Family issues
  
  In early 1813, Beethoven apparently went through a difficult emotional period, and his compositional output dropped. His personal appearance degraded—it had generally been neat—as did his manners in public, notably when dining.
  
  Family issues may have played a part in this. Beethoven had visited his brother Johann at the end of October 1812. He wished to end Johann's cohabitation with Therese Obermayer, a woman who already had an illegitimate child. He was unable to convince Johann to end the relationship and appealed to the local civic and religious authorities, but Johann and Therese married on 8 November.
  
  The illness and eventual death of his brother Kaspar from tuberculosis became an increasing concern. Kaspar had been ill for some time; in 1813 Beethoven lent him 1500 florins, to procure the repayment of which he was ultimately led to complex legal measures. After Kaspar died on 15 November 1815, Beethoven immediately became embroiled in a protracted legal dispute with Kaspar's widow Johanna over custody of their son Karl, then nine years old. Beethoven had successfully applied to Kaspar to have himself named the sole guardian of the boy. A late codicil to Kaspar's will gave him and Johanna joint guardianship. While Beethoven was successful at having his nephew removed from her custody in January 1816, and had him removed to a private school, in 1818 he was again preoccupied with the legal processes around Karl. While giving evidence to the court for the nobility, the Landrechte, Beethoven was unable to prove that he was of noble birth and as a consequence, on 18 December 1818 the case was transferred to the civil magistrate of Vienna, where he lost sole guardianship. He regained custody after intensive legal struggles in 1820. During the years that followed, Beethoven frequently interfered in his nephew's life in what Karl perceived as an overbearing manner.
