Judge, Court of First Instance of Rizal, Branch XXIII, BERNARDO MOLLAT and 
TERESA MOLLAT, respondents.

RELOVA, J .: 
Records  show  that  petitioner  Douglas  B.  Alvir  filed  a  complaint  for  unlawful  detainer 
against  private  respondents  Bernardo  Mollat  and  Teresa  Mollat,  before  the  then 
Municipal  Court  of  San  Juan,  Rizal.  Basis  of  the  complaint  is  that  petitioner  is  the 
registered owner of a residential lot, together with the improvements thereon situated at 
No. 299 Verdun Street, San Juan, Rizal and covered by Transfer Certificate of Title No. 
328543  of  the  Registry  of  Deeds  of  Rizal.  After  said  property  had  been  adjudicated  to 
him as its new owner during the settlement of the estate of his late father Dr. Antonio B. 
Alvir, plaintiff (herein petitioner) wrote private respondents to vacate the premises as he 
and  his  family  are  in  need  of  a  place  to  live.  This  was  followed  by  another  letter 
reiterating his request which, however, the private respondents ignored. 
In their answer, private respondents alleged that in November 1961 the late Dr. Antonio 
B. Alvir entered into a contract of sale with Mr. Howard J. Weber whereby the latter was 
given the right to pay the full purchase price of the property within two (2) years from the 
date  of  the  contract  of  sale;  that  private  respondents  were  allowed  by  Mr.  Weber  to 
occupy the premises before the latter left for the United States; and that they have been 
occupying the property as tenants of said Mr. Weber. 
After  trial,  the  inferior  court  rendered  judgment  in  favor  of  herein  petitioner  Douglas  B. 
Alvir, ordering private respondents Bernardo and Teresa Mollat "to vacate the premises 
occupied by them at No. 299 Verdun Street, San Juan, Rizal and to return possession 
thereof  to  the  plaintiff;  to  pay  to  the  plaintiff  the  monthly  rental  of  P300.00  per  month 
from May 25, 1972 until the said defendants completely vacate the said premises; [and] 
to pay to the plaintiff an additional sum of P500.00 for attorney's fee plus the cost of this 
action." (p. 77, Rollo) 
Appeal  from  the  decision  of  the  inferior  court  was  taken  by  private  respondents  to  the 
then Court of First Instance of Rizal which set aside the decision of the then municipal 
court of San Juan, Rizal and dismissed the complaint. 
Hence, this petition for review by way of certiorari. 
As  found  by  respondent  court,  subject  property  with  an  area  of  502  square  meters  is 
situated  in  San  Juan,  Rizal  and  covered  by  Transfer  Certificate  of  Title  No.  328543  in 
the name of petitioner Douglas B. Alvir as of May 25, 1971 when the estate of his father 
who died in 1951 was settled. 
As  its  owner,  petitioner  contends  that  he  is  entitled  to  the  possession  of  the  premises 
against  the  private  respondents  with  whom  he  has  no  contract  and,  notwithstanding, 
refused to vacate the same. 
On  the  other  hand,  the  private  respondents  claim  that  they  were  authorized  to  stay  in 
the property by Mr. and Mrs. Howard Weber who purchased it from the Alvirs in 1961. 
On this point, respondent court said: 
...  As  early  as  1966,  the  Alvirs  and Weber  seemed  not  to  agree  as  to  the  amount  still 
due  the  Alvirs  from  Weber  which  prompted  Weber  to  deposit  the  amount  which  he 
believed  was  the  maximum  amount  still  due  the  Alvirs  with  the  Associated  Banking 
Corporation.  On  December  1,  1967, Weber wrote  Antonio Alvir,  brother  of  the plaintiff, 
with  respect  to  the  fencing  of  the  property  covered  by  the  deed  of  sale  between  the 
Alvirs  and  Webers  (Exhibit  6-A).  As  testified  to  by  Antonio  Alvir,  Weber  has  been 
pressing Catalina Alvir to deliver the title to the property but Mrs. Alvir refused to do so 
on the ground that the payment made by Weber was delayed. 
From  the  evidence  presented  by  the  defendants.  it  appears  that  defendants  are 
claiming the right to possess the property by virtue of the authority of Weber who claims 
to be the owner of the property as per deed of sale executed by the Alvirs in his favor. 
The  contention  of  the  Alvirs  that  they  are  not  duty  bound  to  surrender  the  title  to  the 
property on the ground that Weber has not complied with the conditions of the sale are 
matters  which  should  be  threshed  out  in  a  separate  proceedings  and  only  until  these 
matters have been clarified can it be said that Weber has no right to the property and, 
therefore, the possession of the defendants under Weber's authority is not lawful

As  a  general  rule,  a  mere  allegation  by  the  defendant  in  an  ejectment  case,  that he  is 
the owner of the real property involved therein, does not and cannot divest the inferior 
court of its jurisdiction over the ejectment suit. However, if it appears during the trial that 
by  the  nature  of  the  proof  presented,  the  question  of  possession  cannot  be  property 
determined  without  settling  that  of  ownership,  then  the  jurisdiction  of  the  court  is  lost 
and  the  action  should  be  dismissed.  (Torres  vs.  Pea,  78  Phil.  231;  Pealosa  vs. 
Garcia, 78 Phil. 245; Cruz vs. Garcia, 79 Phil. 1; Ganaynay vs. Sarmiento, 79 Phil. 36; 
Raymundo  vs.  Santos,  93  Phil.  395;  Dy  Sun  vs.  Brillantes,  93  Phil.  175;  Andres  vs. 
Serrano,  101  Phil.  848;  Songahid  vs.  Cinco, L-14341,  January  29, 1960 as  cited  in 16 
SCRA 677). Plaintiff admitted that before this case was filed, he came across the deed 
of sale by the Alvirs in favor of Weber while sorting out papers relevant to this case (tsn, 
April 6, 1973, pp. 16-17). It is surprising that Weber was not made a party defendant he 
being a party in interest. (pp. 73-74, 75, Rollo) 
In  actions  of  forcible  entry  and  detainer,  the  main  issue  is  possession  de  facto, 
independently of any claim of ownership or possession de jure that either party may set 
forth in his pleading. As incidents of the main issue of possession de facto, the inferior 
court can decide the questions of (a) whether or not the relationship between the parties 
is one of landlord  and tenant; (b) whether or not there is a lease contract between the 
parties,  the  period  of  such  lease  contract  and  whether  or  not  the  lease  contract  has 
already expired; (c) the just and reasonable amount of the rent and the date when it will 
take  effect;  (d)  the  right  of  the  tenant  to  keep  the  premises  against  the  will  of  the 
landlord;  and  (e)  if  the  defendant  has  built  on  the  land  a  substantial  and  valuable 
building and there is no dispute between the parties as to the ownership of the land and 
the building, their rights according to the Civil Code. Defendants' claim of ownership of 
the property from which plaintiff seeks to eject him is not sufficient to divest the inferior 
court  of  its  jurisdiction  over  the  action  of  forcible  entry  and  detainer.  However,  if  it 
appears during the trial that the principal issue relates to the ownership of the property 
in dispute and any question of possession which may be involved necessarily depends 
upon  the  result  of  the  inquiry  into  the  title,  previous  rulings  of  this  Court  are  that  the 
jurisdiction of the municipal or city court is lost and the action should be dismissed. 
We have  at bar  a  case  where,  in  effect,  the  question  of  physical  possession  could  not 
properly  be  determined  without  settling  that  of  lawful  or  de  jure  possession  and  of 
ownership  and  hence,  following  early  doctrine,  the  jurisdiction  of  the  municipal  court 
over  the  ejectment  case  was  lost  and  the  action  should  have  been  dismissed.  As  a 
consequence, respondent court would have no jurisdiction over the case on appeal and 
it  should  have  dismissed  the  case  as  appealed  from  the  municipal  court.  However,  in 
line with Section 11, Rule 40 of the Revised Rules of Court, which reads  
SEC. 11. Lack of jurisdiction.  A case tried by an inferior court without jurisdiction over 
the  subject  matter  shall  be  dismissed  on  appeal  by  the  Court  of  First  Instance.  But 
instead of dismissing the case, the Court of First Instance in the exercise of its original 
jurisdiction, may try the case on the merits if the parties therein file their pleadings and 
go to the trial without any objection to such jurisdiction. 
this  Court  held  in  Saliwan  vs.  Amores,  51  SCRA  329,  337,  that dismissal  "on  the  said 
ground  of  lack  of  appellate  jurisdiction  on  the  part  of  the  lower  court  flowing  from  the 
municipal court's loss of jurisdiction would lead only to 'needless delay and multiplicity of 
suits  in  the  attainment  of  the  same  result'  and  ignores,  as  above  stated,  that  the  case 
was  tried  and  heard  by  the  lower  court  in  the  exercise  of  its  original  jurisdiction  by 
common assent of the parties by virtue of the issues raised by the parties and the proof 
presented by them thereon." In a similar case, the Court ruled that  
As the justice of the peace court of Hagonoy had no jurisdiction to try the case on the 
merits,  the  order  appealed  from  remanding  the  case  to  that  court  must  be,  as  it  is 
hereby, revoked; and, in accord with the precedent established in Cruz et al. vs. Garcia 
et al., 45 Off. Gaz., 227, and the decisions therein cited, the case is ordered returned to 
the  Court  of  First  Instance  of  Bulacan  for  that  court  to  proceed  with  the  trial  in  the 
exercise of its original jurisdiction. (Teodoro vs. Balatbat, et al., 94 Phil. 247, 250). 
ACCORDINGLY, the judgment of respondent judge is hereby REVERSED and the case 
is remanded to the Court of First Instance of Rizal for that court to proceed with the trial 
in the exercise of its original jurisdiction. 
SO ORDERED.
